A method and apparatus for global routing of electronic messages includes maintaining external and internal address information for each user of a messaging system, along with means for associating the external and internal address for any given user. Upon receipt of a signal embodying a message, the messaging system accesses a conversion table to translate the external address for the recipient to its associated internal address. Similarly, for messages being sent to outside recipients, the messaging system accesses a conversion table to translate the internal address for the originator of the message to an associated external address. For messages sent between users of the same system where the originator specifies an external address for the intended recipient, a dual translation may be performed to convert the internal originator address to an external address and the external recipient address to an internal address. Global routing is thus facilitated by freeing system users from having to maintain information about the internal addressing scheme of either their own or other electronic messaging systems.
